Patent EP-0365107-A3 (EP)
IPC: H01L21/331
Filed: 1989-04-21
Abstract: This invention relates to a semiconductor device in 
which a first semiconductor layer (2) is formed on a semi­
conductor anode layer (1) containing a high concentration 
of impurity of a first conductivity type. This first semi­
conductor layer (2) contains an impurity in a lower 
concentration than the impurity concentration of the anode 
layer (1) on which it is formed. A second semiconductor layer 
(3) containing a high concentration of impurity of a second 
conductive type is formed on the first semiconductor layer, 
and a third semiconductor layer (4) containing a low 
concentration of impurity of the second conductive type is 
formed on the second semiconductor layer (3). Impurity regions 
(6) of at least the first conductivity type are formed by 
thermal diffusion in the surface region of this third semi­
conductor layer. During the thermal diffusion, the impurity 
contained in the anode layer diffuses into the first semi­
conductor layer. However, the concentration and thickness 
of the first semiconductor layer (2) are specified so that, 
even after thermal diffusion, the concentration of the second 
 
 
semiconductor layer is not essentially changed, and thus a 
semiconductor device which has a thin, high concentraton 
buffer layer (3) can be provided by this production method.

Title: Endovascular stent apparatus and method
IPC: A61F2/06
Filed: 1990-01-08
Abstract: A stent (10) for reinforcing a vessel wall is constructed 
from a single elongated wire. The wire is first 
bent into a series of tight bends. The wire is then

by half hitch junctions (56) and interconnections which are 
either aligned or spiral around a circumference of the 
stent. The completed stent forms a cylindrical form 
which can be expanded from an initial diameter to a 
larger implanted diameter by application of a radially 
outward force from a balloon catheter (12) or the like.

Abstract: A system and method for the storage of digital information wherein data that
would normally be represented by multiple bits of information is effectively stored at single
memory site within a ROM. This is accomplished by employing a multiple bit-line
memory architecture, in conjunction with a data decoder. With this arrangement it is
possible to store, at a single memory site, information that would have required up to
élog 2 (n(n-1)/2)+1)ù individual memory sites in a conventional ROM (where n is the
number independent of bit-lines connected to an individual memory element in the
invention). The invention is particularly well-suited to what would be considered relatively
low-speed data retrieval systems, such as those adapted to provide audio and/or video to a
user on a real time basis.

Inventor: PROEBSTING ROBERT J
IPC: H01L21/8242
Filed: 1997-07-25
Abstract: A low voltage current source generates low voltage signals for powering
a variable frequency oscillator. The low voltage signals are at a slightly higher
voltage until a negative substrate bias is achieved. The oscillator operates at a
low frequency for low power consumption when no charge pumping is needed
and at a higher frequency when charge pumping is in fact needed or when
charge pumping will most likely be needed. The variable frequency oscillator
controls a timing signal generator which generates the timing signals used to
control the overall operation of the charge pump system. Voltage translation
circuitry translates the low voltage current source signals into higher voltage
signals which are used to translate the substrate voltage from its negative value
to a positive value so that the substrate voltage may be compared to a
reference voltage using a conventional comparator. When the substrate voltage
is above the desired level, the comparator generates a pump activating signals
to a pump signal generator which, in turn, generates the necessary signal to
cause the charge pump to operate.

Abstract: A memory controller (74) and at least one memory module (76,
78, 80) exchange data at high transfer rates by minimizing
clock skew. When writing data to the memory module (76, 78,
80), the memory controller (74) generates a clock signal
that travels along a first clock line segment. The data bus
(84) carries the write data, and the electrical
characteristics of the data bus (84) and first clock line
segment are matched such that incident wavefronts of the
data bus and clock signal arrive at the memory module (76,
78, 80) in fixed relation to one another. When reading data,
the first clock line segment is looped back from the memory
module (76, 78, 80) to the memory controller along a second
clock line segment, with a copy of the clock signal provided
on the second clock line segment. The data bus (84) carries
the read data, and the electrical characteristics of the
data bus and the first clock line segment are matched such
that incident wavefronts of the data bus and clock signal
arrive at the memory controller (74) in fixed relationship
to one another. The present invention provides a substantial
